Abirch tree that is 4 ft tall grows at a rate of 1 ft per year. a larch tree that is 6 ft tall grows at a rate of 0.5 ft per year.
let the variable t represent time in years and h represent height in feet. in how many years will the trees be the same height?
which system of equations can be used to solve this problem?
a.{h=4-t
{h=6-0.5t
b.{h=5t
{h=6.5t
c.{h=1+4t
{h=0.5+6t
d.{h=4+t
{h=6+0.5t

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
